In the scenario of NIC partitions, universally unique identifier
generation may have to consider that, each NIC partition which maps to
a given physical port will have its own MAC address. (The SRIOV VF
network interfaces could probably use PF's MAC address).  But
generation of a universally unique physport identifier would probably
be driver specific.

Right, I agree this has to be driver-specific.

2.  Also, thinking about the default value for 'physport' , could it
be set to zero by default  ? A possible  interface could be

0   ==>   driver did not to set the identifier

quoted

0 ==> driver successfully set the identifier

I think a universally unique identifier would have to be a multibyte
value like a MAC-48, EUI-64 or 128-bit UUID - not a simple number, and
not a fixed length.  The unset value would then have a *length* of zero.
